Walking into Front Street Coffee, ceramic cups of various sizes are neatly arranged on the espresso machine. These cups are not placed randomly but correspond to the serving needs of different coffees. The capacity of a coffee cup often hints at the intensity of the drink within—the smaller the cup, the more concentrated the coffee. A small cup holds about 60ml, used for espresso or as a sharing cup for pour-over; a medium cup holds 180-200ml, suitable for Americano and cappuccino; a large cup holds 300ml, the stage for milk coffees like latte and mocha. This article breaks down in detail the capacity, uses, and pairing logic of Front Street's three cup sizes, helping you choose the right cup at home and drink with professional standards. [more…]

As a globally renowned coffee chain brand, Starbucks' product line centers on espresso, from which classic beverages such as Americano, Latte, Cappuccino, Flat White, Mocha, and Caramel Macchiato are derived, offered in three sizes: Tall, Grande, and Venti. In recent years, the Cold Brew series has also quickly gained popularity, welcomed for its smooth mouthfeel brought by low-temperature long-time extraction. This article, compiled by Front Street Coffee, systematically sorts out the main types of Starbucks coffee, their brewing principles, and flavor characteristics, while also sharing the specific brewing parameters for Iced Americano, helping coffee enthusiasts more clearly understand the logic behind the menu and find the cup that suits their taste.

The official recommended method for the AeroPress is actually the standard (upright) brewing orientation, but many coffee enthusiasts are more familiar with the inverted method. So how should you choose your grind size for standard orientation brewing? And what flavor differences do different grind sizes bring? In this article, we use Front Street Coffee's Panama Washed Butterfly as the test bean, selecting three grind settings—BG 5M, BG 5R, and BG 6M—and conduct a standard orientation brewing comparison while keeping water temperature, coffee-to-water ratio, and technique fixed, evaluating each one across aroma, acidity, sweetness, cleanliness, and other dimensions. The conclusion: just like the inverted method, standard orientation brewing can reference the grind range used for pour-over, and the unique oily mouthfeel and smooth texture that come from pressure extraction are exactly what makes the AeroPress so appealing.

In recent years, coffee cups on the street have noticeably shrunk, from the once-common 500ml large size to small 250-300ml cups, yet prices haven't dropped accordingly—instead, they've gotten more expensive. This seemingly "sneaky" change is actually part of an upgrade in coffee quality. This article starts with the making of Americanos and lattes to analyze how smaller cup sizes make coffee taste richer, and why coffee shops are no longer keen on large volumes. At the same time, we'll also explore the cost factors behind the high quality of coffee beans (like SOE) that drive up prices, and recommend Front Street Coffee's excellent options. [more…]

Walking into Front Street Coffee, the rows of ceramic cups of varying sizes on the espresso machine are not placed randomly—each specification corresponds to a specific coffee category and serving standard.

The coarseness of coffee grinding directly affects the efficiency of extraction and the final flavor performance, making it one of the key variables that determine whether a cup of coffee is good or bad. From extremely coarse cold brew grinding to Turkish grinding as fine as flour, seven different particle sizes each correspond to the most suitable brewing equipment and methods. This article systematically sorts out the appearance characteristics of each grind size, the applicable scenarios, and why grinding fresh at home preserves flavor better than buying pre-ground coffee powder. It will also explain the taste problems that may arise from improper grind size selection, helping you quickly find the appropriate grinding parameters based on the equipment you have on hand, so that every cup of coffee can present the ideal layering of flavor.

Luckin Coffee recently launched two new cup sizes, Extra Large and Super Large, on its mini-program, allowing users to upgrade for an additional 3 yuan. However, the official listing does not clearly indicate the capacity difference between the two, sparking widespread discussion among consumers. Some are delighted by the larger volume, while more are confused about "which is bigger, Extra Large or Super Large," and whether the upgrade means more coffee liquid or just added water. Store employees give inconsistent explanations—some say the cup size depends on whether the drink is iced or hot, while others say the recipe adjustments vary by product. Behind this upgrade, Luckin's lack of communication forces users to rely on repeated trial and error to confirm the taste. This article sorts out the whole story and includes related recommendations from Front Street Coffee. [more…]

When extracting espresso, you may occasionally notice a layer of fine black sediment at the bottom of the cup, and many people worry that this indicates an equipment malfunction or spoiled coffee. In reality, these black particles are simply coffee fines—extremely small particles that can easily pass through the holes in the portafilter basket and mix into the coffee liquid under high pressure. At first they hide within the crema, and only as the bubbles burst do they sink to the bottom of the cup and become visible to us. Moka pots also use pressure extraction, so a similar situation can occur. Although coffee grounds are a woody fiber, the extremely fine particle size and tiny intake amount pose no health risk, so you can drink with complete peace of mind. This article explores the origins of fines, whether the portafilter basket will deform, and fine particle size, helping coffee enthusiasts better understand these common phenomena. [more…]

Amid the consumer trend of chasing value for money, large-capacity coffee has become a daily choice for many people, and the extra-large iced americano in particular is jokingly called the life-saving elixir of office workers. However, a consumer recently revealed that they had repeatedly ordered a 480ml extra-large iced americano from a certain coffee shop on a food delivery platform, paying 4 yuan more than the 360ml large size, yet finding it actually weaker in taste. Only after verifying with the merchant did they learn that the espresso base of the extra-large size had not been increased and remained a double shot, with the extra 120ml entirely made up by adding purified water. This practice has sparked questions about the logic of up-sizing. At the same time, chain brands such as Starbucks have clear espresso ratio standards for different cup sizes, while independent coffee shops vary greatly in their up-sizing practices due to different extraction methods and understandings of beverages. Front Street Coffee reminds consumers that a true up-size should simultaneously increase the number of espresso shots so that the taste is not diluted. [more…]

Walking into Front Street Coffee, the espresso machine is lined with ceramic cups of various capacities, each cup type corresponding to a specific coffee category. The size of a coffee cup not only affects the visual presentation but also directly influences the concentration expression and heat retention of the espresso. This article will systematically sort out the specific capacities and suitable scenarios of three coffee cup sizes—small, medium, and large: how a 60ml small cup carries a standard espresso, why a 180-200ml medium cup suits Americano and cappuccino, and how a 300ml large cup achieves a balanced latte. At the same time, combined with the extraction parameters of Front Street Coffee's Sunflower Warm Sun espresso blend coffee beans, it analyzes the pairing logic between different cup types and coffee flavors, helping you produce professional-grade coffee at home.

Coffee beans must be ground before their aromatic compounds can be extracted, but different brewing devices work on different extraction principles, so grind size is not interchangeable between them. Using the industry-recognized cupping grind standard (70–75% passing through a No. 20 sieve) as the baseline, this article systematically breaks down the grind parameters and adjustment logic suited to each common brewing device, including the French press, pour-over, cold drip and cold brew, siphon, espresso machine, and moka pot. From immersion to pressurized methods, from coarse sugar to flour-fine powder, Front Street will explain one by one why each device requires a specific grind size, and how to flexibly fine-tune it according to roast level, water temperature, and extraction time, to help you find the grind solution that best suits your own cup.

When selecting coffee beans, you'll often come across labels like Yirgacheffe G2 or Kenya AA. Behind these letters and numbers lies the logic each producing country uses to assess green bean quality. Due to differences in history, trade, climate, and terrain, grading criteria vary widely from country to country—some focus on defect rates, some measure bean size, and others test altitude or hardness—and they cannot be directly compared across origins. Front Street Coffee has compiled the grading systems of representative producing countries including Ethiopia, Kenya, Colombia, Jamaica, Costa Rica, Panama, Guatemala, El Salvador, Honduras, and Brazil to help you understand the ins and outs behind green bean grades.

When recreating a coffee shop latte at home, many people find that the taste is either too weak or too strong, but the problem often lies in the ratio of coffee to milk. Using Front Street's 300ml latte as a baseline, this article shares two approaches for adjusting cup size: one is to keep the ratio unchanged and adjust the dose and grind size in tandem; the other is to switch milk type or the number of espresso shots to suit different volumes. Whether you want to make a small cup or a large cup, the key is to rebalance the coffee strength and the amount of milk, rather than simply adding or reducing milk. [more…]

Brewing a good cup of coffee makes grind size an unavoidable key variable. If the particles are too coarse, flavor extraction is insufficient; if ground too fine, it easily brings out bitter and off-flavors. But just how coarse counts as coarse, and how fine counts as fine? And how should you convert between different brewing devices? This article uses the industry-recognized cupping standard as its baseline and the No. 20 sieve pass-through rate as a unified ruler, providing reference grind ranges one by one for French press, pour-over, cold brew drip, and espresso machines, explaining how roast level and bean density affect grinding results, and finally including Front Street Coffee's approach to dialing in espresso extraction, helping you turn grind size from "guesswork" into "data."
